The defending champions are Gabriel Hemlinger of Massachusetts and Amanda LaBelle of Rockland in the marathon, and Knud Hermansen of Old Town and Cary Buterbaugh of South Portland in the accompanying 15K.

It’s not too late to sign up, as runners looking to compete in the marathon have until Saturday at 8 p.m. to do so. Saturday registration will take place 3-8 p.m. at the Sugarloaf Base Lodge, and only cash or checks will be accepted as forms of payment.

No race-day marathon registration will take place, but those wanting to sign up for the 15K can do so prior to the start of the race, from 6:15 to 7 a.m.

Some other vital race-day info: Transportation from the finish line to the start via shuttle bus will be available for all runners in both races.

For marathoners, buses will depart from Tranten’s Parking Lot in Kingfield, located across the street from the finish line on Route 27, at 5:30 a.m. sharp, while a bus will also pick up runners from the Sugarloaf Marathon hotel lobby at 5:45.

The 15K shuttle will leave Tranten’s at 6 a.m., and there will be a shuttle after both races for those who need to be dropped off at the Sugarloaf Mountain Hotel. Baggage transportation is also available.
